Update 17/02 05:20 PT: Seagate has contacted us to notify us that not all components of its Mozaic 3+ HDDs are made in-house. Some are outsourced.
When Seagate formally introduced its first high-volume hard disk drives featuring its heat-assisted magnetic recording (HAMR), it implied that all of their components would be produced in-house. However, a new report from Nikkei says that Seagate has teamed up with Sony Group to produce laser diodes for its HAMR write heads. This may signal that Seagate will not put all its eggs in one basket and will rely on laser diodes from Sony as a secondary source.
